DESCRIPTION

The TDA 8140 is a monolithic integrated circuit de-

signed to drive the horizontal deflection power tran-

sistor.

The current source characteristic of this device is

adapted to the on-linear current gain behaviour of

the power transistor providing a minimum power

dissipation. The TDA8140 is internally protected

against short circuit and thermal overload.
